# LuaLogService:new

The constructor for a `LuaLogService` object (creates a new `LuaLogService`).

IMPORTANT: Do not create a new log service to write messages to log types that are defined in the Facebook Connector configuration file. Instead use the same log service as Facebook Connector, by calling get_log_service, or obtain a `LuaLog` object through the function get_log.

## Syntax

    LuaLogService:new( config )

## Arguments

Argument | Description
--- | ---
`config` | (LuaConfig) The configuration object to read the logging settings from. You can obtain a LuaConfig object through the function get_config.

## Returns

(LuaLogService). The new `LuaLogService` object.

## Example

The following example creates a `LuaLogService` object to write log messages to a custom log file named `lua.log`. Declare the log service globally to avoid a `LuaLogService` object being created every time the script runs. For example, if you are writing a Lua script to use with a connector or CFS, create the `LuaLogService` outside the `handler` function. Otherwise, the server creates a `LuaLogService` object for every document that is processed.

    local luaConfigString = [===[
    [Logging]
    LogLevel=FULL
    0=LuaLogStream

    [LuaLogStream]
    LogTypeCSVs=lua
    LogFile=lua.log
    ]===]

    local config = LuaConfig:new(luaConfigString)

    -- global log service instance for Lua log stream
    luaLogService = LuaLogService:new(config)

    local luaLog = luaLogService:get_log("lua")
    luaLog:write_line(log_level_normal(), "running Lua script")
